How can I use Unity FSM for my in-game behaviour?

Salut!

I have a draft for anti-aircraft gun behaviour. It is not controlled by a player, but by AI.

There is no much animation in 3D model: only turning the turret and elevating the barrel. May be some muzzle flashes with sounds.

Is there any way to use Unity3D FSM capabilities to code my AA-gun?

If possible, how can I do it? What should I study?

Thank you!
